MTL Safety Barrier SD32X
The Crouse-Hinds series MTL SD range is a series of surge protection devices combining unparalleled packing densities, application versatility, proven reliable hybrid circuitry, simple installation and optional ‘loop disconnect’ facilities – features which make the range the ultimate surge protection solution for process equipment, I/O systems and communications networks.
The exceptionally high packing densities are the consequence of an ultra-slim footprint for individual modules which can thus "double-up" as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection.
SDX models
Available in 7V, 16V, 32V and 55V versions (SD07X, SD16X, SD32X and SD55X respectively) are suitable for a wide range of applications including THCs, 4-20mA loops, shut-down systems and fire and gas detectors.
